To all whom it may concern; I I

Be it known that L'C n-L A. JonNsoN, a subject of the King of Sweden, residing at lyorcester, inthe county of 'Worcester and State of Massachusetts, have invented a,

new and useful Take-Up Block, of whichthe following ,is a specification.

Thisinvention relatesto a take up block for, wire galvanizing, tinning and annealing In this class of machines the wire does not ride up the drunrnornially as it does on a wire drawing machine drum and consequently the operators have to go around the plant and push up the wire from time to time. This involves unnecessary expense for attendance of the machines but tl' e principal disadvantage is that it is done irregularly and consequently when bundle of wire is wound on the block it is all snarled up and is not in good condition for The principal object of this invention is to provide automatic and regularly acting means for moving the wire up the surface of the blocka little at a time at regular intervals so as to leave the' wire in a smooth untanglecl condition onth'e block and avoid the waste of time heretofore thought necessary. W

Reference is to be had to the accon'ipanyingdrawings, in which Fig. 1 is a plan o'fa structed in accordance with this-invention shown partly in section; and

Fig. 2 is acentral sectional view of the same on the line 2 2 of Fig. 1.

I have not shown the machine to which the device is applied, but it can be used on galvanizing, tinning or annealing machines for handling wire and the invention relates to the drum on which thewire is wound. In fact the drum with this improvement is capable of general use. This drum is shown as usual fixed by its hub 12011 a shaft 11 rotated in any desired way. 'This drum is of the usual character having a conical surface on which the wire coils'as the machine operates.

For the purpose of the present invention, I fix on the hub 12 of the drum a cover plate 13 having three arms 14 radiating therefrom and integral with thiscov'er plate as shown. Each of these arms ispr'ovided "with a perforation for receiving a tangeir tial shait oi; stud swimm r mounted take] up "block 0011- woncnsun, aussacuusmi'ns.

on each stud is a lever 16 "having-a 1011.17 at the bottom engaging the exterior surface of acam 18 which is mounted in fixed position below thedrum andcauses the levers each rotation ofthe drum in opposition to their springs 19. Each lever has a pawl 20 resting on a ratchet wheel 21 mounted to 16' to be rocked on their a'X'es oncc during H freely rotate on the shait1j5. Therefore at each complete revolution of the drum the ratchet wheel is advaneed'one tooth; H

On the ratchet wheeljis fixed a wireengaging and'lifting plate If there are twenty teeth on the ratchet wheel 21, the

p a e 2: th reon w l, come a ound once i That is, when twenty twenty revolutions. convolutions of wire are wound on thedru n, and prO ect out through a slot 23 in, the

.side of the drum, As it rises" it engages the lower strands of the wire 011* the drum and lifts them, starting at the dotted line position shown attire right in Fig. These twenty convolutions are lifted-by the three teeth 22' spaced equally around the *drnm and not alloperating simultaneouslybut all operating at thesaIne revolution. In this way the wine is slid up" the surface of the.

drum gently and yet positively and it will not tangle up on the surfaceb-ut the-twenty convolutions' ordinarily will together.

There is a gravity actuated stop pawl2 l for preventing the wheel QTHIOV-lBg lMIQl K- wardly. .l P

Fixedly mounted on each arm 1 1 is a support 25 having a pointed end projecting through the slot 23. The lower side of the projecting'end of the arm 25 is slanted so that the wire will pass over it when forced up positively by the tooth 22, the upper edge of which at that time is horizontal or tipped up slightly so that the wire will not be disengaged from it on account of that angle. The wire is pushed up this incline and over the support 25 which thereafter holds the wire up in that position and prevents its. falling back by gravity after once being pushed beyond it. It is to be noted that the pushing of the wire over'this projecting end of the support 25 requires a little give in the wire. Usually it is wound slack enough so that this will take place without In this way the wire is automatically pushed up the drum as many times as may be necessary, kept from getting tangled up, andheld in a position above that at which the new wire is being wound. The saving in labor is also an important feature.

Although I have illustrated and described only a single form of the invention I am aware of the fact that modifications can be made therein by any person skilled in the art without departing from the scope of the invention as expressed in the claims. Therefore I do not wish to be limited to all the details of construction herein shown and described but-VVhat I do claim is 1. The combination with a take up block for a wire galvanizing, tinning or annealing machine, of means located inside the block and projecting through the walls thereof for moving a plurality of coils of wire along the surface of the block every time the block makes a predetermined number of revolutions.

2. In a take up block for a wire working machine, the combination with the block itself, of a plurality of means projecting through the wall of the block for moving a coil of wire along the surface of the block, and means for operating said means one at a time during a single rotation of the drum- 3. The combination with a take up block for a wire galvanizing, tinning or annealing machine, said block having slots through its walls, of movable means projecting through said slots for periodically raising the coils on the outside of the block and relatively stationary means for holding them in elevated position.

4. The combination with a rotary wire drawing block, of means for consecutively engaging the lower part of a coil of wire thereon at a plurality of points around the circumference and raising the coil at those points one at a time.

5. The combination with a take up block for a wire galvanizing, tinning or annealing machine, and a shaft for rotating it, of a. stationary cam located outside the drum, a plurality of arms inside the drum. a series of levers pivoted on said arms and adapted to be operated once during each revolution of the drum by said cam, a pawl on each lever, a ratchet wheel pivoted on the axis of each lever in a positionto be actuated in a step by step manner by the pawl, said ratchet wheel having a lifting plate projecting through the wall of the drum for raising the coil of wire along the surface of the drum once during a predetermined number of revolutions of the drum. 7

6. The combination with a take up block for a wire galvanizing, tinning or annealing machine, and a shaft at the center thereof for rotating it, of a stationary cam located outside the drum, a plurality of arms inside the drum extending from the hub thereof, a series of levers pivoted on said arms and adapted to be operated once during each revolution of the drum by said cam, a pawl on each lever, a ratchet wheel pivoted on the axis of each lever in a position to be actuated in a step by step manner by the pawl, said ratchet wheel having a plate projecting through the wall of the drum for raising the coil of wire along the surface of the drum once during a predetermined number of revolutions of the drum, and a fixed arm extending through the wall of the drum in a position to receive and hold the coils of wire pushed upwardly by said plate on the ratchet wheel, said ratchet wheels being arranged to operate one after the other during one revolution of the drum.

In testimony whereof I have hereunto affixed my signature.
